I have owned the older dated pair of these for 3 years and only now have the wires broken and caused a problem with the hearing.
They sound brilliant, nice quality and comfortable to wear. blocking out enough background noise so you can listen to music uninterrupted.
The fact they fold away has been handy for carry when out and about. i originally bought these headphones for playing along to music when drumming, and so that shows how well they do infact block out the external noise as these worked well for this activity.
They are reasonably small for headphones, and although quite clearly visible they are not as chunky or heavy as many other styles and makes out there.
Overall i would definitely recommend these headphones as i am planning on replacing my old ones with this updated version asap.
